Application tiled June 30,1904. Serial No. 214,780,

Be it known that i', iinNnYll. BncHMAN, of Battlecreeli, in the county ol." Calhoun and State oi' lriichigan, have invented certain new and useful improvements in Multicolor Duplex Printing; and l hereby declare that the followingl is a full, clear, and exact description thereof, reference being; had to the accompanying drawings, which Aforni part of this specilcation.

This invention is an improvement in printinpypresscs ol the well-known duplex AHatbed web-perfecting type; and the object of this invention is to enable the duplex press to produce eight pages or less in colorsvin other words, to make a multicolor duplex printing-machine. In order to do this` it is necessary to provide a duplex press with an additional printing-couple which may be and preferably is conveniently located parallel with and directly above the usual bed or' the duplex press, and the reciprocatingI cylinder oi' this third printing-couple may be connected with and operated by the cross-heads of the ordinary duplex press. The web feeding, looping, and delivering mechanism employed in this press are substantially the same as those of the ordinary duplex press, a t'ew additional web-guidingrolls beingl added for the purpose of Crying` the web when it is to be printed in colors through the additional printing mechanism.

ll do not deem it necessary to illustrate all the parts in detail in the accompanyingl drawing, as the duplex press is well known, and any one familiar therewith will be able to construct and operate the present invention Vfrom the followingI description in connection with the drawing attached hereto, and i will rcfer to the claims for summaries of the essential `features or' the present invention for which protection is desired.

The acconnpanyingl drawing` represents a rolls by which the web may be ted into the machine troni the web-roll "di, it being' an eight-page web in a lull-sized `press. .lf'he web then passes under a guide-roll 9, then up over a lower looping-roll L down under a guide-roll Mi, over cross-head guide f1 down between lower cylinder H and bed L, up over right-hand cross-head guide f to and under (,:oaXing-roll mi, up over another (forming-roll m, back over upper cross-head guidej"Il down between upper cylinder Hi and upper bed ./lX on over opposite cross-head guide f bachY to guide iii, down under upper looping-roll l, then up over guide 2 to the delivery-roll O, which is driven by suitable gearing;n indicated in the drawinc' by the leed-roll. The C) web is directed by roll C) down under a guide 3, said web having` been previously slitted by suitable means (as by a cutter on roll il', which coacts with roll Q) into two parts w and fin. From the guide one-halt, in', of the web be passed rearward over deflector et and suitable guides to the folder E The parts thus tar described are practical identical in construction and mode or' open tion witl the ordinary duplex press and are substantially such as are shown and described in the patent to Cox., No. 478,503, July 5ry .i892`r and the reference-letters used on the drawing correspond to the reference-letters on similar parts shown in said patent. parts which i. shall now describe are those which arc added to that press in order to cnable it to add colors to the web printed on the lower beds and produce a multicolor .sheet L`he other hal w, oi: the eight-page web (in cases where it is only desired to print 'four or the eight in colors) is led up over a guide 5 and then passed 1lorward between the roll G and roll @2, bac-l; over a guide 6, down under a guide 7, up over a looping-roll 8, which is mounted in the same looping-trame as the rolls I W. it then passes down under a guide 7 and passes (above the cylinder H' and guides nl'11'lf)toaguide7b. ltthen passes up over a coaXer-roll 7"', forward., and then back over a cross-head guide/f", down under between a third cylinder H" and bed 1, up

over cross-head guidefii, back over a guide 7d, down under n, looping-roll 8" (in the sinne l freine :is ioopiin beck to :'ud between the roll (li :ind which it is guides 7" 'l pcrimposed upon the other hnlf m, of the web und both are vfolded together.

llhe cylinder lili: end hed /f ere practically duplicates of the othcrlmdsnnd cylinders end :irc nrrznig'ed, prcfcrnbly7 parallel end in vertical nlinenn-)nt therewith., :is shown.

The looping-rolls S il :ind the guides il T" T 7 direct the web w between the bed find cylinder /5 und ll," in sul)stuntizillyv the seine nninner er the innin web is fed between the lower ocds und cylinders,

it will be obi-served from the foregoing' de- Scription thnt the eiglit-lisnee web is printed on the lower hed /f/ end is then perfected on the middle bed .71l in the instance esplnined. Vv here onlgf foin' pages r-re to be printed in colors, the web divided :it the roll 3, ind e 'four-ginge web or one-huit) is carried on di.- rect to 'the folder l1", while the other four-pego web (or one-helf) is returned over the top bed /lff1 where the perfected web is imprinted in colors, suitnblc bhinl: spaces hnvine been left on the forms on the lower beds for this purpose.

lf it is (.lcsircd to print more than four 'pages in colors, the entire web (or eight-page web) inegi* he 'passed boel( through the uuichine in the line of the web Aw. Vln other words.l insteed of the web being'sepzirntcd ut the guide il he entire web is passed buck over roll 5 into und through thc uppe printing' niet-,henisni, following the course of the part of the web 'wf in the drawing.

i ne loopi A -rolls/ l 3 there ell mounted in the sonic freine end operated synchronously by the sinne mechau'iism which is used to operete the looping-rolls l in the (,n'dinnry duplex press` :ind prncticnllv the deliveryv mechanism of the old duplex press is utilized to feed in the return length of web f//i through the upper bed :ind cylinder. fin sdditionel cylinder 11) nnigv be added to the deliver-5Y meehanisin, so es to utilize the upper surface of the roll t, as :fr feed-surface.

'Ehe three beds muy be used to print nu ordinary eight-pego. peper in hlncl, if it is dcsired, by Cividini;l the weh di either before or lifter it posses the lirst bed :ind cylinder l-ii.. 'i the web would then be pusscd between the bed /r and cylinder l'l,11nd the other heli' of the web would go directly up to the guide il and be nissegl then between the bed /ffi und cylinder to be perfected thereby, the two ports of thc web being assembled :it the folder. l do not, however1 in this :ipplicntioi'i clnini of my pre sent invention being 'to produce eight pages or less in colors on the du plof; press, und this .l :iccmnphsh hv the simple addition to such press o f en ext-rn bed und cylindernnd l folder9 ineens for directingv the other of seid fed out sind passes thence over j i to the folder F, where it is suii few entrey guiding' devices (indicated b); il,

i numernls in the drawing) and by the pecniie thremling; of thc wein utilizing" the web feeding' und looping mechanism of the old duplex press us e ineens for operating the web in the zulditionnl multicolor-printing couple.

l do not restrict myself to placing the colorforrns on the upper bed, ns obriouslj.v they could be 'placed on one of the other beds. if it is preferred., in which cese, of course.l lhe bleek or perfec tingA color would have to be run on the top bed. l

lr'leving thus described how the full eightpe-gc web may be perfected on the press, it seems unnecessary7 to explain et length how u smaller number of neges could be perfected f in colors on this press1 es smeller pepers could be perfected in either of the methods ebove described, und other arrangements might suggest themselves to the pressvnen.

Having thus described my invention, what l cleirn es new, und desire to secure b5; Letters Patent, is
